nitrh tetra ANTI-FRICTION OIL.

an scant marsh in in its: itetters a test are making put at its Klimt.

TO ALL WHOM IT MAY CONCERN:

It is a well-known fact that friction upon all substances generates heat and electric action; and that electricity generated by diifercnt substances is different in its qualities, and is known as resinous and vitreous or positive and negative. At the point where positive and negative conditions of electricity neutralize, heat will be generated, as all heat results from electric action. When two pieces of iron are rubbed together they generate an electric force which is transformed into heat; but if We introduce between them sulphur, orelements equivalent in electric conditions, we will prevent friction of the two metallic surfaces, the friction then being iron upon sulphurous compounds, changing the electric condition and thermal state, and consequently its result. Thus, to overcome friction and its eiiects, I incorporate with oleaginous substances, various materials producing an anti-friction compound, to be used for lubricating machinery. Many of the vegetable oils and gums are not easily oxidized when combined with some of the hydro-carbons, and can be made to undergo a process of vulcanization while in a fluid state when sulphur is present dissolved in the hydro-carbons. Thus, body may be given to lubricating oils, which act in many ways, preventing friction; such as the combination of sulphur,

forming sulphnrets with the oxides and worn metals, as antimony, lead, zinc, tin, &c., used in friction-boxes,

and known as the Babbitt and other compounds. Some of the substances in this compound have the power of' dissolving oxidized oils, and thereby setting free the worn metallic particles therein contained. These combine with the sulphur, forming sulphurets, which, united with the other elements of the compound, form one of the most valuable anti-friction mixtures known. Thus it will be seen that this mixture will prevent what mechanicsterm gumming, or remove it, where it has taken place. My invention consists in compounding certain articles in such a manner as to secure the above-named results.

To enable others skilled to make and use my invention, I will proceed to describe its combination and operation. 4

Take of the products of gas tar known as tuluole, fylole, cumole, and cymole, which distill over from a temperature of 240 to 480 place these in a closed vessel with two pounds of sulphur, and raise the temperature to 240; agitate for a few minutes, then add two quarts of linseed oil, and again agitate, still maintaining the temperature; then add five (5) pounds of tallow, and two (2) quarts of lard oil; again agitate until thoroughly mixed and dissolved, then remove to cool to the temperature of 1609'. Take petroleum and place in a still, distill over until the temperature reaches 220, when it is allowed to cool and settle; decantor draw off without disturbing the sediment. Add forty gallons of this oil to the above compound, and again raise the temperature to about 210 or 220; then allow it to cool, when it is lit for use.

I have indicated above the proper proportions I prefer; but these may be modified somewhat, adapting them to heavy and light machinery.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A material for lubricating machinery, formed by combining sulphurwith hyro-carbon oils, tars, or their equivalents, substantially as described. 4 i

2. The combination of linseedoil with the products of gas tar and sulphur.

3. The combination of any of the petroleum series of hydro-carbons with the gas-tar series, as herein described, for the purpose set forth.

4. The combination of the petroleum and gas-tar series of the hydro-carbons with sulphur, for the purpose set forth.
